A unique rebus+

I'd call this a rebus+ (complexity, visual components, lateral thinking). The answer is a letter.

Short story of the problem:

I was happy, I felt I finally invented something solvable, easy, and good. After telling the solution to my girlfriend, she frowned at me, and said: "This is not solvable, not easy and..not good. Sorry.." ... BUT I accept only opinions from PSE! So let's get started!

Hint:

The unique rebus requires a unique hint. I hereby reveal the structure of he problem, let's see how it works in this company of problem solvers. It's virtually a biconceptual (and "games" related) unified context, where abstraction leads to word A and visual (multiple,redundant) clues lead to word B, where B⊆A and the solution is A\B.

Hint2

The object (a game) and the "type" inside the object refers to word B, the "meaning" (and another game) will lead to word A. And then solve as per Hint1.

Hint3

What's the difference between dog and god?

• Could it possibly be rot13(Oernxvat Onq)?

Is it the letter:

S?

Word A:

The difference between dog and god is that dog is god backwards.

This is possibly a reference to the game Backwords.

Word B:

Both the image and the typeface are a reference to the Etch-a-Sketch.

This iconic toy is known for drawing on the back of a plastic screen using a stylus and aluminum powder. Thus, the word being clued could be draw + back = drawback.

Applying the instructions from Hint 1:

[a,a,b,c,d,k,r,s,w]/[a,a,b,c,d,k,r,w] = s

Per the hint

A is palindrome -- "dog god"
B is plate -- the picture resembles a license plate
t is the only letter found in plate that is not found in palindrome
the answer is the letter T

• Re what you say the picture resembles - that's very country dependent. Mar 13, 2020 at 21:06
• It's not a license plate, but indeed resembles an object. That is one of the clues. Mar 14, 2020 at 14:35
• The picture resembles an rot13(rgpu-n-fxrgpu). Dec 8, 2021 at 19:38

Okay, maybe I'm taking this too literally, but:

is it the letter R

Explanation:

The letters on either side of the palindrome cancel each other out except for a sliver of the first "d" which looks like a Latin Rotunda "Ꝛ" or the letter "R".

When you say in your first hint:

B⊆A and the solution is A\B

I suppose you more mean:

A-B? I may be off, and perhaps it's just a mistake in the image, but I cant imagine how you divide a text by a text unless you mean one cancels the other out leaving the remainder, in which case I would say it is more "A-B". And perhaps your title is ironic calling it a "Rebus+" when it's more a "Rebus-", but maybe I'm reading in too much.

Anyway, Interesting puzzle!

• In set theory, both A\B and A-B can be used to indicate the difference of two sets. Dec 10, 2021 at 15:19
